Words are important, but even more important is what is really in our hearts, for it is from the abundance of our hearts that we speak. If our hearts are pure, filled with the Spirit, the love, joy, and peace of God then good flows from our hearts like a river through our words and actions. If however our hearts are filled with hate, bitterness, and selfishness, then it's best to keep our mouths shut because we only hurt others and sow destruction for our lives. So, bi filled with the Spirit of God!
So true Sherman . But if we are spirit filled Christians we would want to put only pure thoughts into our minds in order to glorify our Lord . If the Holy Spirit is convicting of us of stuff that is not edifying to the spirit , then don't do it . We have to be very careful what we fill our minds with .
If our hearts are filled with as you say hate , bitterness , and selfishness then the Holy Spirit cannot live there .
